    Nope. All injected petrol engines have a fuel cut on overrun. No fuel, nada, niente, zero. And if the weight of the car on a downhill stretch is sufficient, it will drive the fuelless engine as long as you like.

    We've had our 69 plate Leon 1.5tsi EvO for 3 weeks now. All I can say is so far no kangarooing and smooth idle. Also. It's averaging 52mpg as opposed to our 67 Ibiza 1.0 tsi 115 which was only managing 48mpg. Overall we are impressed the engine is very quiet and silky smooth.

    That’s good to know. Hopefully your vehicle has the latest software modification referred to in this thread - just waiting for my A3 to have this software modification:

    Same here, 69 plate, FR trim, mystery blue, also no kangarooing or any other issue. Lovely engine, maybe a bit slow as it's 130hp version but of course I was aware of that prior to purchase. Very happy with the engine and overall car.

    Well there are certain conditions that must be met, but in general it is true, injecting is disabled on the overrun, and has been for many many years for many manufacturers, one way to check is to check the instantaneous MPG when on the overrun with a heated up engine and engine revs over roughly 2000rpm.

    My 19 plate 1.5tsi 150 Evo DSG auto with 1200 miles on the clock is absolutely smooth under all conditions and returns low to mid 50's mpg.

    Interestingly the 66 plate 1.2tsi 110 (cambelt engine) manual I had previously did hesitate from stationary in first gear and did it from new.
